Quantifying the Value Propositions of MPLS Evolution

This paper presents a network and business modeling approach and a case study to quantify the value propositions of three evolution scenarios to NGN. For this, we develop detailed and flexible network models, design and configurations to replicate various architectures, scaling patterns and possible migration steps in a variety of large networks. This is integrated with modelling to analyze and compare cost-effectiveness of the evolution scenarios by quantifying their capital expenditures (CapEx), operational expenses (OpEx), and new sources of revenue (e.g., IP VPN) made possible by MPLS.
